The equation components are measured by means of a ball mill circuit survey and a laboratory test of the ore grindability. As can be seen in the equation, the mill power (kW) being used ‘effectively’ (on coarse particles) is simply the product of the mill power and the CSE, which is the percentage of the mill solids which are coarse.
